Brazil in Africa: Another Emerging Power in the Continent?

This paper develops three basic arguments. First, it presents the basic underpinnings of Brazilian diplomacy in the past half century, concentrating on the changes adopted in the 1980s and the 1990s up to the foreign policy put forward by Lula`s government (2003-2009). It recognises that Lula`s foreign policy represents a step forward, especially where Africa is concerned. However, it does not seem to be clear whether the Brazilian economy has enough strength to sustain such a foreign policy, as is shown in the second part of the paper. This is indeed the case if comparisons are made with India, China and even South Africa, when the latter`s regional role is considered. Finally, an effort is made to summarise the recent political cooperation established between Brazil and African countries as well as to present an overview of Brazil`s trade and investment relations both with the region as a whole and with some important individual partners. Once this picture is established, we investigate whether these realmsdiplomatic/political and economictake independent tracks, or if they do interact in a coherent manner. Africa remained deep inside Brazil and Brazilians, not as something external to ourselves. But as a mythic space; neither geographical, nor historical.

The Benefits of Sugarcane Chain Development in Africa

As consumers continue to be concerned about the future of sustainable agriculture and the scarcity of natural resources, biofuels can be an important component of the "people" solution through job creation, development and interiorizing economic activities of a country through moving money from cities into rural areas. The Brazilian sugarcane industry is well developed in terms of corporate social responsibility and can serve as an example for other countries such as Africa. The objective of this article is to show how sugar cane can contribute to the development of Africa by producing renewable fuel for use in booming African cities. A supply of sugar can be developed for use in local markets and exports. Other opportunities exist to produce bioelectricity from the process of burning the bagasse and other new products such as plastic and diesel. In the case of Ethanol, this fuel has proven to be the most efficient in competing with gasoline in the last 40 years, and Africa may gain with a strategic plan on ethanol.

The construction of the African perspective: a history of the General History of Africa project (Unesco)

This article analyzes the construction of the African perspective in the General History of Africa project (GHA), focusing on the period between 1965 and 1979. With the participation of over two hundred international experts under the auspices of Unesco, this was one of the greatest intellectual projects of the twentieth century. Based on primary sources, this analysis emphasizes the internal conflicts involved in the construction of the African perspective as a hegemonic line of thought in the GHA. Two critical moments of the project were found in the investigation: the controversial years (1972-78), and the pragmatic years (1978-82). As a result of these disputes, theoretical and methodological parameters were constructed, in addition to eight volumes of material published in the 1980s, and recently republished in Brazil.

The characteristics of VIM-1-producing Klebsiella pneumoniae from South Africa

A study was designed to characterize a carbapenem-resistant Klebsiella pneumoniae (KPSA01) isolated from a patient in Gauteng, South Africa without recent travel outside South Africa. Molecular characterization was done using isoelectric focusing, polymerase chain reaction and sequencing for bla(VIM), bla(IMP), bla(NDM), bla(CTX-Ms), bla(OXAs), bla(TEMs), and bla(SHV), plasmid-mediated quinolone resistance determinants, multilocus sequencing typing, plasmid replicon typing, and addiction factors. KPSA01 produced VIM-1 and belonged to the newly described sequence type ST569. The plasmid that harboured bla(VIM) typed within the narrow host range IncF replicon group, contained the aadA1 gene cassette, and tested positive for the vagCD and ccdAB addiction systems. This is the first report of VIM-1-producing K. pneumoniae outside Europe. It is important that surveillance studies be undertaken in Africa to determine if VIM-1-producing K. pneumoniae are present in significant numbers.

Phylogeography of Rift Valley Fever Virus in Africa Reveals Multiple Introductions in Senegal and Mauritania

Rift Valley Fever (RVF) virus (Family Bunyaviridae) is an arthropod-borne RNA virus that infects primarily domestic ruminants and occasionally humans. RVF epizootics are characterized by numerous abortions and mortality among young animals. In humans, the illness is usually characterized by a mild self-limited febrile illness, which could progress to more serious complications. RVF virus is widespread and endemic in many regions of Africa. In Western Africa, several outbreaks have been reported since 1987 when the first major one occurred at the frontier of Senegal and Mauritania. Aiming to evaluate the spreading and molecular epidemiology in these countries, RVFV isolates from 1944 to 2008 obtained from 18 localities in Senegal and Mauritania and 15 other countries were investigated. Our results suggest that a more intense viral activity possibly took place during the last century compared to the recent past and that at least 5 introductions of RVFV took place in Senegal and Mauritania from distant African regions. Moreover, Barkedji in Senegal was possibly a hub associated with the three distinct entries of RVFV in West Africa.

The types of Lygistorrhinidae and Mycetophilidae (Diptera: Bibionomorpha) in the KwaZulu-Natal Museum, Pietermaritzburg, South Africa

An annotated list of the type specimens of Lygistorrhinidae and Mycetophilidae (Diptera: Bibionomorpha) at the KwaZulu-Natal Museum, Pietermaritzburg, South Africa is provided. Information on 54 type specimens, three lygistorrhinids and 51 mycetophilids, with details of labels and actual preservation of the specimens is furnished. Locality data are georeferenced and habitus images of type specimens are provided.

Validation and comparison of two soil-vegetation-atmosphere transfer models for tropical Africa

This study aims to compare and validate two soil-vegetation-atmosphere-transfer (SVAT) schemes: TERRA-ML and the Community Land Model (CLM). Both SVAT schemes are run in standalone mode (decoupled from an atmospheric model) and forced with meteorological in-situ measurements obtained at several tropical African sites. Model performance is quantified by comparing simulated sensible and latent heat fluxes with eddy-covariance measurements. Our analysis indicates that the Community Land Model corresponds more closely to the micrometeorological observations, reflecting the advantages of the higher model complexity and physical realism. Deficiencies in TERRA-ML are addressed and its performance is improved: (1) adjusting input data (root depth) to region-specific values (tropical evergreen forest) resolves dry-season underestimation of evapotranspiration; (2) adjusting the leaf area index and albedo (depending on hard-coded model constants) resolves overestimations of both latent and sensible heat fluxes; and (3) an unrealistic flux partitioning caused by overestimated superficial water contents is reduced by adjusting the hydraulic conductivity parameterization. CLM is by default more versatile in its global application on different vegetation types and climates. On the other hand, with its lower degree of complexity, TERRA-ML is much less computationally demanding, which leads to faster calculation times in a coupled climate simulation.

Condom use at last sexual relationship among adolescents of Santiago Island, Cape Verde, - West Africa

Objective: To estimate factors associated with condom use at last sexual intercourse among adolescents. Methods: Cross-sectional study of a representative sample of 368 sexually active adolescents aged 13-17 years from eight public high schools on Santiago Island, Cape Verde, 2007. The level of significance was 5.0% obtained from logistic regression, considering the association between condom use and socio-demographic, sexual and reproductive variables. Results: The prevalence of condom use at last sexual intercourse was 94.9%. Factors associated with condom use at last sexual relationship were: non-Catholic religion (OR=0.68, 95%CI: 0.52; 0.88) and affective-sexual partnership before the interview (OR=5.15, 95%CI: 1.79; 14.80). Conclusions: There was a high prevalence of condom use at last sexual intercourse of adolescents.
